F12 Auxiliary switch/change over switch/auxiliary contact

F12 Series switch is one component of high-voltage switch. It's often used for controling the switching on or switching off of high-voltages spring mechinism, and indicate the interlocking signal.

Main features:

To control the DC contact of DC 220V/110V close coil or breaking coil, it could reach 20A when the breaking current is DC 220V.The double-break bridging contact is made of silver alloy. Compared with the current anxiliary switch, it contacts directly, resists oxidation, and resists corrosion.It is of simple structure and long lifetime. Being an ideal product, its also easy to use.

Application conditions

Ambient Temperature (-40oC+40oC)Height above Sea Level (h≤2500m)Mean relative air humidity in 24 hours (T≤95%)Mean water vopour pressure in 24 hours (≤2.2Kpa)Mean monthly relative humidity(≤90%)Mean monthly water vopour pressure (≤1.8Kpa), includes the dew covered on the surface of the products, which is caused by the changes in temperature.Acceleration (a ≤15m/s²)
